little more than half way across the disk; the hasc hefore these hristles 

 and a narrow longitudinal area beneath the apical part of the venation 

 bare ; speculum reaching from the latter area obliqueh' to the basal area, 

 much narrowed above and overhung by the bristle-like hairs ; marginal 

 fringe rather short and moderately dense ; marginal vein about twice as 

 long as thick, equal to the stigmal. the postmarginal somewhat shorter 

 and forming an acute angle with the stigmal ; marginal and postmarginal 

 veins with a row of six bristle-like hairs of which the one at the apex 

 of the postmarginal is much the longest. 



Head, abdomen and thorax except the scutellum smooth and highly 

 polished, the scutellum with an extremely minute, granular alutaceous 

 sculpture ; surface of the antennae rather opaque, the scape with rela- 

 tively coarse reticulations. Eyes with a short, fine and rather thick pile ; 

 frontovertex with four rows of very fine, but rather long, pale-colored 

 hair of which the orbital rows are inclined forward, the others back- 

 ward ; mesoscutum with similar, sparse, scattered hairs, the apical margin 

 near the middle. with a pair of longer, bristle-like black hairs; scutellum 

 with two pairs of still stouter, longer black bristles, one pair near apex, 

 the other but slightly further apart just I)ehind the middle, the disk also 

 with a few fine hairs. Dorsal margin of the pedicel and flagellum and 

 the ventral apices of the pedicel and funicle joints provided with numer- 

 ous, black. l)ristle-like hairs, tlie sides of the club with similar, shorter 

 hairs. 



Length: .78 to 1.18 mm. 



General color of head, thorax and venter al)out ochraceous orange 

 (Ridgway) ; the face and cheeks paler yellow with a rathe; wide trans- 

 verse fuscous to blackish band across their middle, passing through the 

 base of the antennae and curving upward on the median facial promi- 

 nence : an olilique band on each side of the prosternum extending for- 

 ward from the coxae, black ; frontoverte.x. mesoscutum and mesopleura 

 washed with a distinct but not very strong purplish luster ; propodeum 

 and mctanotum blackish on each side of the middle, the metapleura with 

 an oval to oblong spot on the upper part, brilliant, metallic, pale green ; 

 abdomen e.xcept the venter l)lack with a bluish luster medially at the 

 base, the sides on the basal half l)rilHant, l)right green, the sides very 

 broadly on the apical half about antimony yellow (Ridgway). Antennae 

 concolorous with the frontovertex, the radicle joint and ventral margin 

 of the scape n.irrowly lilack. Legs somewhat paler yellow tli.m tlie tho- 

 rax with the apex of the tarsi, the first joint of the hind tarsi and two 

 annuli on the hind tibiae black, the first tibial band situated close to tiie 

 base, the second just beyond the middle. Wings subhyaline : a broad 

 area across the disk opposite the apical third of the ven;ition .'.nd tlie 

 extreme base smoky; apical i)art of disk beyond tlio von.ntion slightly 

 infuscated and more deeply so in ;i narrow hand encircling the infiated 

 area, leaving the apical margin clear: veins yellowish with the marginal
